WINDOW-CLEANER.

Application filed August 1, 1914. Serial N 0. 854,505.

To all whom it may concern:

Be it known that I, FRANCIS S. NEYDHART,

a subject of the Emperor of Austria-Hungary, and a resident of West Hoboken, in the county of Hudson and State of New Jersey, have invented a new and Improved Window-Cleaner, of which the following is a full, clear, and exact description.

This invention relates to brushing and scrubbing, and has particular reference to devices for cleaning windows.

Among the objects of the invention is to provide a device of the character indicated which is adapted to be manipulated conveniently and effectively by hand and for operation upon both sides of the window pane simultaneously.

More definitely stated, the invention comprises a two-part frame, the parts being pivoted together at a single point, one of the parts including a rigid handle'cooperating with the adjacent pivoted part so as to vary the degree of pressure upon the window pane and each of said pivoted parts having connected to it a peculiarly formed block or head to which are detachably connected a plurality of cloths with nieans for readily detaching a soiled cloth or removing it out of the way so as to present a fresh cloth to the work.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference in-' dicate corresponding parts in all the views, and in which Figure 1 is a side elevation of a preferred embodiment of the invention showing the same in use upon a window pane, the window sash being in section; Fig. 2 is a rear elevation of one of the cloth holding heads; Fig. 3 is a transverse sectional detail on the line 3-3 of Fig. 2; Fig. 4 is a detail indieating one of the many" difi'erent ways in which cleansing cloths may be easily ap lied to the heads; and Fig. 5 is a view of a ragment of the device taken in the direction of the arrow 5 shown in Fig. 1. I

The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general designof the mechanism, may be Specification of Letters Patent.

closely adjacent the point of connection bea tween the lever 11 and the lower portion of theframe 10. The member 14 in effect constitutes a lever of the third class when gripped, as shown in the drawings, by the operators hand between. the pivot 15 and the shoulder member 16. This member 14 is rigid with respect to the shoulder 16 and comprises a pair of bars between which the lever 11 is disposed, constituting a most effective hand grip for the operator. It will be observed that the frame members 13 and 14 cooperate with each other, as indi cated, and constitute an open frame which is adapted to span the window sash bringing the shoulder members 13 and 16'on opposite sides of the window pane and directed substantially toward each other. The width between the bars 10 and 14 is sufiicient to give ample room for manipulation of the device with respect to the window sash.

The heads or swab carrying members shown at 17 may be variously constructed, but a preferred form of the same is shown in Fig. 2, the same comprising a substantially rectangular block having a flat inner or working face 17'. As a simple and re liable means forvpivotally connecting each block to its shoulder'member, the outer or rear face of the block is provided with a pair of parallel lugs 18 between which the shoulder member extends, and a pivot 19 secures these parts together, allowing a certain amount of free pivotal movement of both of the blocks with respect to each other and the window pane. That is to say; they lower portion of the main frame, or that portion of the frame which is remote from the blocks, is adapted to be moved transversely of the plane of the window pane free manipulation of the same in all directions so as to bring the working faces of the blocks readily into contact with all parts of the window pane. The blocks 17 may With the invention thus far described, its

operation may be briefly set forth as fol lows: The two blocks carried by the shoulder members 13 and 16 of the two main frame portions are separated from each other sufciently far to pass over they window sash and into contact with opposite sides of the window pane. The operator then grasps the lever 11 and frame 14 at any convenient point along the lever 11. By the grip, herein indicated, of the operators hand upon the parts of the frame, he may move the entire structure up and down or transversely or in any other direction so as to wipe the cleansing members thoroughly over the wmdow pane. Obviously with the lever 11 and the frame member 14: related as shown and disposed normally at a slight angle from each other, a powerful grip is provided whereby the operator, upon increasing his pressure, may increase the pressure between the cleansing members and the window pane proportionally. In other words, the operator has free command of the device as to its manipulation over the window pane and at the same time may increase or decrease the direct pressure upon the window pane according to the requirements or exigencies of any particular case. p

As shown herein I adapt the heads or blocks 17 for holding in a detachable manner a plurality of cleansing cloths 20. A bundle or group of these cloths of suitable size are secured together along one edge as by means of open rings 21 or pins 22. These fastening devices 21 'or 22 are preferably of such a nature as' to provide an open metallic loop for the purpose of booking the adjacent edge of the mass of cloths over keepers 23, preferably two in number, along one edge of each block, preferably the inner edge. The mass of cloths is then brought around'flatly upon the face 17' of the block and the free edges thereof are all brought together beneath a temporary fastener shown preferably in the form of'a yoke 24 acted upon by springs 25. The yoke 24 is provided with a loop 24: whereby the operator may, by the use of his finger, lift the ,yoke to manipulate the cloths in putting them in place or in shifting them. If desired, the upper edge of the outer face of each block maybe roughened or fitted with a corrugated member 26 to increase the friction between the block and the cloths in holding them in place. At any convenient place, preferably adjacent the shoulder members 13 and 16, are arranged spring catches 27 beneath which a soiled cloth may be caught temporarily. and held while the operation continues with afresh cloth. lln

treason other words, with a grou of cloths at tached to each block or hea as shown. after the operation has progressed sufficiently to soil the cloths, the operator will lift the yoke 24 and separate a soiled cloth from the remainder of the group and swing it down around the axis of the fasteners 21 or 22 and swing it across the shoulder member and snub it beneath the fastener 27. The bulk of cloths then remaining clean may be used as before over a fresh surface. After all of the cloths have been soiled, they may be readily slipped from the head by releasing the yoke 24 from'the last cloth and then slipping all of the cloths from the keepers 23 and fasteners 27. So long as a single cloth remains in place over the active face 17 of a block, the group of soiled cloths cannot become displaced or lost from the keepers 23.

Havingthus described my invention, ll claim as new and desire to secure by Letters Patent 1. The herein described window cleaning device comprising, in combination with a pair of frame members mova'bly related to each other, 'a flat faced block connected to each of said frame members, abundlc of cloths attached together along one edge by metal fasteners providing open loops, a pair of hooks having open ends secured adjacent one edge of the block and with which said loops are engaged, the free portions of the cloths being passed over the flat face of the block and looped over the edge thereof remote from said hooks, and a spring pressed yoke gripping said free edges of the cloths.

2. In a window cleaner, an open frame frame members extending from the pivot along the lever member and constituting in connection therewith a lever of the third class and including a pair of bars between which the rigidly connected. lever is posed, the lever members-being adapted to be grasped by one hand of the operator for manipulatingv the frame and simultaneously varying the pressure upon the window pane, and a pair of cleansing members connected to the ends of the frame. members remote from ,the pivot. I
